@@grahamwynde1176 did you mean to post at top level?

[@teqai]

If you're using Python anyway, you can align those measurements pretty easily by minimizing root mean square error. Basically, subtract one line from the other, square the differences, average over all of them (or just sum them*), take the root of that number (not really necessary*). Do that for different offsets (shift one of the lines along the x axis), choose the offset with the lowest resulting RMSE. * (for the purpose of finding the offset with minimal error)

[@philipk4475]

Favero knocks it out of the park again. They are an italian company which makes affordable, top quality and top functioning electronics for cycling. Colour me impressed... Their first gen power meter (the BePro) was a huge PITA to set up and I had issues with accuracy that were never resolved even after a calibration, but with the Assioma they really knocked it out of the park and I think they've upped the ante once again with this one. I will have to start setting money aside because I will want this on my gravel bike or a future XC bike for sure!

[@andraslukoviczki519]

hahh, yes, the BePro is overmeasured the power with 5-15% by default (due to the very poor factory slope calibration), and because lack of auto-angle monitoring, if the axle is rotating a bit, the installing angle is changing (which is needed to the power calculation), but it remained on the old value, the whole power calculation was off (you had to reverse pedaling, that set the new angle value, but it could rotate a tiny bit day by day... so the best was to do this reverse pedaling everyday , or throw out the pedals). in the Assioma the better slope calibration and the auto-angle monitoring help "lightyears" in POV of power accuracy.

[@indianajonze]

Great video, Favero make some good kit (unlike a lot of the bike products on the market) I picked up their road pedals back in 2018, they have been faultless despite a number of bad crashes in things like crit races (although I did need replace the pedals bodies from the crashes, easy, cheap, powers still accurate) + Batteries still work like a gem.

Ive been using assioma duo Shi pedal axles inside shimano M520. Ive had a few nasty pedal strikes without problems, obviously not as ideal as these (and not warrantied) but still works for me. Pretty sure they weigh a ton more than those too! Maybe someday I will upgrade to those. lighter and cheaper than the Garmin pedals. Also at 14:18 "Let me just put my pen on" - Oh boy I thought I was watching Hambini for a second.

[@alexanderhardy971]

Favero are claiming stack height is 11.2 mm yet Shimano states their XTR is 15.1 mm. You mentioned that you measured the Favero as being taller though? UPDATE : the favero pedals true stack height is 17.9 mm. Favero don't include cleats and shimano do.

[@josipX]

I have the Assioma Duo-shi mated with Ultegra pedals on three bikes. On all three bikes I have radial play to the point of it clicking and being very annoying when riding. I changed the pedals after one of them split and regreased the spindles which helped, but the play soon came back. Great power meter but the mating with Shimano pedals aint great as you get the feeling that there is a gap between the cleat and the pedal.

I'm just going to say this: I have the Garmins and they are ok as power meters but awful as pedals. They squeak unless they are completely covered in grease. They are loose, no matter how much you tighten the tension on the cleats. I have had 2 replacements and they still squeak. Garmin makes absolutely terrible SPD pedal bodies. I will be buying assiomas as soon as they are available where I live.

Do you think it's possible they release an updated road pedal with all the tech inside the pedal instead of having the pod? Do you think they will? - Not sure I see a reason to to be honest, none of the pedals seem to have issues with breaking, weather sealing, etc.

[@joseafonso5671]

How about their performance after crashing them during rides with rocks and roots? I know we don't ride to crash pedals into rocks or roots , but in XC marathon that happens very often...and that is my number one concern about doing this big upgrad€...

[@Tuffjobs]

My stages road crank power meter shows zero watts when I stand up to climb hills or when I sit and apply my max power on hills. It’s not the well known battery contact issue. I see there’s a “run a magnet over the gyro”fix for generation 3. I have have generation 2. What the most likely explanation? The bike is rocking laterally side to side when I’m out of the saddle. Could it be this lateral movement? Or the rapid increase in torque? Or the lower angular velocity due to lower cadence? It’s annoying because these are my times of highest power and all I’m seeing is zero. It works fine the rest of the time!

[@rorylogan4473]

why is no-one talking about the pedal/cleat float with these?! just got a set, IMO the amount of float is obscene. how did you find it?

[@PeakTorque]

Are you using new shimano cleats? Mine feel the exact same as xt, although i tightened the tensions spring a little vs xt, as the release tension felt lower. I’ve had mine for 1.5yrs now, was an original tester.

[@luigibirillo6629]

How do they calculate the correct tangential force? How do they know where the pedal is at any given moment of the pedal stroke? Do you have to zero with the crank arms in perfect vertical position?

[@luigibirillo6629]

Nobody seems to know anything about this source of error

[@grahambleach]

How positive did you find the cleat engagement vs a Shimano SPD pedal? I have the Rally XCs and that is the biggest annoyance for me. Real SPDs have a satisfying engagement click and the Rallys are vague and sometimes you can’t tell when the cleat is engaged, despite adjusting tension. I’ve been waiting for Favero to make SPD pedals!

[@PeakTorque]

Blindfolded, could not tell the difference between this and shimano. Like I said in another comment at first I found the default tensions a bit low on mx but on this final version it seems higher and the exact same as XT. I may have been wrong though - it may have been the same all along.

[@graffix11us]

Did you test the single or double sided pedals? If single, how often did you have to flip the pedal or miss a clip in?

[@PeakTorque]

They’re all double sided! Both side power meter. The mx1 is power meter on one pedal only

[@ulrikmortensen9426]

Hi PT, you and Favero are super reliable in your respective works. A great review. But how do you mount the pedals to the crank arms with the correct torque? On The Assioma Duos it is easy to use a torque wrench with an Allen key bit. But here the mounting seems to be using a 15 mm pedal wrench.

[@PeakTorque]

Correct its a 15mm wrench. I never used a torque wrench, just did up reasonably tight. No problems in 12 months, constantly swapping bikes.

[@andraslukoviczki519]

when i bought the Garmin Vector 1 in 2013 sept, i had to buy a torque wrench (Holex) and a 15mm wrench adapter, i had to make this thinner with milling machine with a few mms because lack of space. but the ParkTools made a cheap and narrow-headed version (TW-1) but there was a world-wide shortage then, probably due to the Vectors :D Luckily i dont have the Vectors since many years, i have just more Power2Max NGs , but the torque wrench is good for the normal pedals and for the Rotor cranks (with allen/hex adapters)

[@roberttobin7342]

You use a crows-foot adaptor. When the original Vector 1 came out the retailers of 15mm crows foot adaptors sold out throughout the country for a few months. Eventually Garmin started including them with the pedals. For Vector 1&2 the correct tightening torque was important to the accuracy of the product. When we start selling Assioma Pro MX we will offer a crows foot adaptor as an option with the product if people want to make sure they are tightening them to specification.The recommended tightening torque of 30-40Nm is probably harder than most people do their pedals normally.

[@andraslukoviczki519]

@@roberttobin7342 its name "open jaw plug-in head" what i bought , the crow-foot a bit different , but yes, the proper tightening is more important than sometimes the people thinks.

Re: Quarq accuracy. Dunno how old yours is. But the current (and fairly old design) DFour is definitely less accurate (under-reads) and less responsive when compared to my latest gen Sigeyi and Xcadey, Elite Diretto XR, and borrowed Assiomas.

[@andraslukoviczki519]

Quarqs usually overreads :) (but could be single other cases..) but if you can do an accurate static weight test at home, you can get it more accurate. the problem is the old and dumb strain gauge in it, the Assioma and P2M NG, or maybe any newer chinese miracle have much newer and smarter strain gauge with active temp compensation, the Quarq is similar tech as the old Power2Max TypeS, more then 10-15 years old... if You can simulate a very big temp change near to the bike, you can compare these powermeters' behaviour, i made a few tests few years ago on winter indoor, the results were very spectacular. if the temp is constant or just tiny changes, almost all powermeters are measuring on acceptable level or "good"

[@ericpmoss]

Regarding “the peanut” and non-instantaneous angular velocity reading, would oval chainrings compensate for that?

[@philipk4475]

That's what they claim. Might make it less. Doesn't make a re performance difference though, otherwise the WT would be on it. It's a preference thing - your leg/brain adjusts accordingly

[@andraslukoviczki519]

yes, the Assioma and the Power2Max NG are using IAV, so they measure the same with round and oval chainrings. the other powermeters are on the market not, 3-4% higher measurement with ovals (Osym) or if You have very kicking pedaling technique instead of "perfect" circle pedaling , then also these "cheap toys" are overmeasuring the power.

[@luigibirillo6629]

​@@andraslukoviczki519 Why is power overestimated if non-round chainrings give a more uniform angular velocity?

[@andraslukoviczki519]

"power meters assume that you turn the pedals at steady speed throughout each pedal stroke revolution. The problem is, oval chainrings cause your crank velocity to change during each pedal stroke, as they limit the time in the dead spot and lengthen the time in the power phase" in short. btw i suggest everybody to learn to pedal smooth and fluently in circle with round rings, this oval is just hiding your problem, but not solving it. it has no power gain , otherwise everybody in the pro peloton would use it... but as we know, especially in cycling industry , if you do a good marketing, you can sell anything worthless for high price also 😂

@@PeakTorque needs to be even power distribution across the range. My L/R balance for a ride is usually in the range 49/51 to 51/49, but zone 2 it is around 47/53 and above threshold 53/47 (10mm leg length difference, quads and glutes engage differently accord to physio).

1 sec recording provides fairly low resolution. It’s a shame there’s no way to record uninterrupted output of power registered by PMs.

@@PeakTorque these power meters record faster than once per sec though, it's more about how this data is stored/probed. You can test it yourself by connecting two devices (e.g. watch and computer) and recording same session on both. You'll see that the power numbers don't match.

[@andraslukoviczki519]

@@channul4887 the transmitting signals are on 4HZ or 8HZ via ANT+ but usually the powermeters are sending the SAME (internally averaged) power value during these 250ms or 125ms rate (there are a very few exceptions, but these 4 or 8x same datas are needed as redundancy for perfect signal quality, the signal interferences can ruin the transmit if you send 4 different power values within 1s and the had unit need to process all the 4 different values, there will be too much dropouts), the instant (so at the end of the ride only the max power) power values are could be a bit different if one of the head unit picks up before the value change , and the other is after the change, but the avgpower is ALWAYS THE TOTALLY SAME for a ride (if there are no dropouts , of course). If you can read the raw ANT+ signals from the powermeters , it is clearly seeing. yes, there are non-standard method to get faster data rate (honestly, higher resolutions needs only for sprinting, nothing elsewhere), even on ANT or easier to get it via BT (like the Stages has/had the 64HZ high speed mode via mobile app into csv,)

very explicit information - some very technical😅just a quick question: how accurate is the MX-1? I don't have any imbalances between legs and I do believe that in XC due to the differences in the terrain , the balance is not an issue because it's natural that someone applies a little bit more power with one of the legs. I do believe that overall value and normalized power is far more important. Therefore, I am inquiring you about the accuracy of the "single model".

[@boostenmkiv]

I totally trust your thoughts on this because you clearly are an intelligent engineer. The pedals are not rated for Enduro, does a rear suspension potentially lessen the load on the pedals vs. a hardtail mtb or gravel bike coming down a very chunky gravel "road"?

Wonder if new Assiomas without pod everything in the axle are on the way?

[@uknowbass]

Not sure about these, but I believe most power meters use strain gauges in groups of 4.

[@danschgt]

zwift power has the same tool for Free, it work just fine

[@Timo-qb1gf]

Peaky Torque pedals then?

[@CatManDoSocial]

Great review. They will definitely be what I get if I ever decide to get power on my MTB.

[@uiroxcv]

When will we have the road version?

[@JoseG373]

And they are sold out……..

[@OVOCNYCHECK]

there we go

[@ΘάνατοςΧορτοφάγος]

Ok, i'm sold, i will get these

[@michaelthorp2867]

Great review, thanks.

[@treyquattro]

impressive giving a technical presentation with no interruptions while riding a gravel bike! How is the front camera being supported? Drone? Very out-front mount?

[@PeakTorque]

It’s an X3 camera on a carbon pole. Still very flexy. Got a much stiffer support for the next one where I’m mounting a brace on the fork crown mudguard mount!

[@treyquattro]

@@PeakTorque I did wonder if it wasn't mounted to the fork

[@chriswhite5665]

Do you think the different cleat binding plates had an effect in your crash, where the Favero maybe didn't release when a Shimano would have?

[@PeakTorque]

No. It was a horror crash. The bindings are almost identical to XT in the way they clip and release. If you were blindfolded you couldn’t tell the difference. In the early days I would almost say the default tension (without adjusting the screw) was lower on the mx than XT but whether they have updated that or not I’m not sure but on the latest set they feel absolutely identical.

[@PeakTorque]

@@e.con5712 nah i like being connected. They would scare me!

[@channul4887]

@@e.con5712 I never understood why SH-56's even exist. To me they are dangerous AF, since you're not in full control of when they disconnect and when they disconnect suddenly, e.g. when you bunny hop, you're not going to connect back straight away - basically losing control on the disconnected side (or sides if you're unlucky and both unclip). It's like having a flat pedal but worse.

[@luketoms6110]

What's the release date for these in the UK. ??

[@PeakTorque]

It was supposed to be yesterday, don't know what they are up to. Probably some marketing/forecasting tactic, no idea.

[@luketoms6110]

@@PeakTorque they are not available on their website either.

[@luketoms6110]

@@PeakTorque Do you think they will bring out a Shi and Keo pedal body to upgrade to a road set up if wanted to like Garmin do.

[@roberttobin7342]

They haven't started selling them yet and we as retailers cant take pre orders until they have enough stock to start shipping. It is going to be a few weeks at least before you can place an order or anything starts shipping (I spoke with the owner today). When Assioma launched in 2017 they were still a relatively unknown company so demand didn't overload them and they had stock (and all the spare parts) at launch point. Now they are probably the market leader in power pedals they know demand is going to be massive to start with.

[@lee1987923]

Is spd less effective in power transfer compared to spd-sl?

[@PeakTorque]

No. Absolutely not.

[@thedownunderverse]

@@PeakTorque Assuming the shoe tread interfaces with the pedal body correctly, sure. But that's not guaranteed at all and it's a lucky dip depending on which shoe you use. When the tread wears, it no longer makes contact, the efficiency drops and the contact gets sloppier and sloppier. Fine for MTB but horrendous for road and fast gravel.

[@JulianKent]

Get stiffer shoes with longer tread then?

[@thedownunderverse]

@@JulianKent it’s a crap design. great for mud clearance and ease of clip in/out, terrible otherwise. also the float is way too much, very sloppy

[@channul4887]

@@thedownunderverse do you have data to back your claims and how much of a "loss" are we talking about? Something that would bother world tour riders during TDF, i.e. 1.5 sec over 4 hours? GCN or any other youtube grifter's "opinion" doesn't count as scientific facts.

[@nienkerk1]

Love your content but having a hard time enjoying listening while you’re riding your bike. Please stop riding and talking/reviewing/explaining at the same time. Just find a chair and a quiet place 🙏

[@BrianRPaterson]

It's never bothered me. I ran this one again and I can hear fine. No need for the comfy chair.

[@martinhotan8946]

rather cool product BUT all modells are "out of stock"

[@BrianRPaterson]

I've been waiting ages for a decent SPD-style power pedal and these look pretty impressive. I don't mind waiting a few months, or longer, to get something good. Plus, it'll give some time for any less obvious faults to show up in vlogs and forums.

[@roberttobin7342]

They haven't started selling them yet. You will have to wait for a few weeks.
